Arsenal hero Martin Keown feels Liverpool will miss Sadio Mane at Manchester United on Sunday.
Keown wrote for the Daily Mail: "Liverpool have looked tired recently.
"They cover so much ground but have not got the same energy levels as earlier in the season. On Sunday, I am sure they will find it, and the return of Philippe Coutinho is vital. But Liverpool will miss Sadio Mane.
"The trio of Mane, Coutinho and Roberto Firmino is so effective. Coutinho makes great runs, Mane has pace and Firmino presses and holds the ball up. Without Mane they do not have the same balance."
